The UPS is equipped with 3 ‘option slots’ (rear panel, 12-14). In the most left slot (12) an RS232/contact interface card is factory installed. See 5.1. In the middle slot (13) additional Relay or SNMP plug-in Cards can be installed. The most right slot (14) allows easy installation of an RPA plug–in Card (Redundant Parallel Operation).
6.1RS232 / contact interface
The RS232/Contact interface (9-pole, sub D, rear panel, 12a) enables advanced communication between the UPS and e.g. a personal computer. An interface kit (cable and software) is delivered with the UPS. The software supports most common operating systems incl. Novell, UNIX, VMS, Windows 3 - 95/98/2000 - NT, IBM OS/2, LINUX, has a modular and layered architecture and works for all degrees of network complexity: stand-alone, multi-vendor networks and large managed networks.
During a power failure the UPS software takes a number of actions: processes are stopped, open files are closed and unattended systems will be shut down in a controlled way. When the utility power returns, the systems will automatically start up and will be up and running as soon as possible.

6.2Emergency shutdown
The emergency shutdown connector is located on the RS232/contact interface card (12). Be sure that the UPS is switched off, and remove the card from the unit*. Remove the wire from connector J3 (pin 3 and 4). Install the wiring of a normally closed contact to connector J3 (pin 3 and 4). Re-install the RS232 interface card. If during normal operation of the UPS the contact is opened, the UPS will shut down. To restart the unit, restore the connection and turn the UPS off and on again.
* If the card is removed during normal operation the UPS will shut down.
6.3Relay Card (optional)
The relay plug-in card can be installed in the middle option slot (rear panel, 13). The card is provided with four potential free contacts representing: battery low, bypass active, utility failure and general alarm. For more information please refer to the user manual that comes with the interface card.
6.4SNMP Interface (optional)
This SNMP plug-in card can be installed in the middle option slot (rear panel, 13). The card makes the UPS ‘SNMP manageable’: it allows the data interface to be connected directly to an Ethernet network (thin coax, twisted pair, AUI). For more information please refer to the user manual that comes with the interface card. When this option is installed the RS232 communication link is no longer available.
